3. External Use.
We want to provide you with excellent service and to offer you a great selection - we primarily sell merchandise, not information. We do not sell, rent, trade, license or otherwise disclose your specific personal information or financial information to anyone, except that:
As do most Internet retailers, we sometimes use others to perform specific functions on our behalf. When we disclose information to these service providers, we disclose information to help them to perform their service. For example, in order to deliver products to you, we must share some information. We partner with third parties (such as the U.S. Postal Service, United Parcel Service, and Federal Express) to ship products, to ensure delivery, and so that we can obtain feedback, improve the quality of our service, and measure and improve the quality of the service of the third party. In the example of shippers, we provide them some personally identifiable information such as your name, shipping address, email, and phone number.
Similarly, to help you buy products and provide customer service to you, we must provide your credit card number to financial-services corporations such as credit-card processors and issuers. When we submit your credit card number for authorization, we use state-of-the-art data encryption to protect your information. (More on this below in Data Security.)
We may be required to disclose such information in response to requests from law-enforcement officials conducting investigations; subpoenas; a court order; or if we are otherwise required to disclose such information by law. We also will release personal information where disclosure is necessary to protect our legal rights, enforce our Terms of Use or other agreements, or to protect ourselves or others. For example, we may share information to reduce the risk of fraud or if someone uses or attempts to use our Site for illegal reasons or to commit fraud.
We will not sell (or trade or rent) personally identifiable information to other companies as part of our regular course of business. However, it's possible that we might acquire or merge with or be acquired by another company or that we might dispose of some or all of our assets. If that happens, your personal information may be disclosed to another company, but that disclosure will be subject to the Privacy Policy in effect.
We may share non-personal information (such as the number of daily visitors to a particular web page, or the size of an order placed on a certain date) with third parties such as advertising partners. This information does not directly personally identify you or any user.
Data Security
This Site incorporates physical, electronic, and administrative procedures to safeguard the confidentiality of your personal information, including Secure Sockets Layer ("SSL") for all financial transactions through this Site. We use SSL encryption to protect your personal information online, and we also take several steps to protect your personal information in our facilities. Access to your personal information is restricted. Only employees who need access to your personal information to perform a specific job are granted access to your personal information. Finally, we rely on third-party service providers for the physical security of some of our computer hardware. We believe that their security procedures are adequate. For example, when you visit our Site, you access servers that are kept in a secure physical environment, behind a locked cage and an electronic firewall. While we use industry-standard precautions to safeguard your personal information, we cannot guarantee complete security. 100% complete security does not presently exist anywhere online or offline.
Opt Out/Corrections
Upon your request, we will (a) correct or update your personal information; (b) stop sending emails to your email address; and/or (c) disable your account to prevent any future purchases through that account. You can make these requests at the customer information section of this Site or by emailing your request to AmericanForestry.com's Customer Support department at info@americanforestry.com. Please do not email your credit-card number or other sensitive information.
Offline Collection, Use & Disclosure of Information
As you might expect from AmericanForestry.com, the majority of information that we collect is obtained through our Site, and this Privacy Policy applies only to that online collection of personal information. We also collect information offline, where we also try to protect the privacy of you personal information. One example involves someone calling us to place an order or to ask questions. When someone calls, we will ask only for the personal information we need in order to place the order or to answer the question. When we need to store information (such as order information), we will enter it into our database through SSL encryption. (See the Data Security section above for more information). Another example involves faxes. If you fax something to us, we will act upon the fax and then either store it a locked repository or we will shred the fax if there is no need to retain the information. There are other ways we could learn of personal information offline (for example, we suppose someone could send us a letter including some return address information), and this Policy doesn't discuss or try to predict all of those methods or uses. As we mentioned, we primarily sell merchandise, not information, and we will try to treat offline collection, uses, and disclosures consistently with our relevant online practices.
Update to this Policy
If we change or update this Privacy Policy, we will post changes and updates on this Site so that you will always be aware of what information we collect, use and disclose. We encourage you to review this Privacy Policy from time to time so you will know if the Privacy Policy has been changed or updated.

Determining Guide Bar & Saw Chain Compatibility
In order to figure out if the Guide Bar and Saw Chain you plan to use together are compatible, there are (3) key specifications that you must match up:
(1) Pitch, (2) Gauge, and (3) Drive Link Count.
Your bar and saw chain must have the same exact specifications, otherwise they will not work together. Please see the rest of this guide, and/or utilize the in-page navigation links to determine how you will find these exact specifications.
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/BarChainFit_d9333737-2fa4-4c16-bfe7-b25c3a7934fb.png?v=1673900251" />
FYI, many retailers call out the length of the saw chain (in inches) as a starting point for customers, but please be aware: determining compatibility solely by length is the most common reason we see for incorrectly ordered saw chains. While a saw chain and guide bar may be the same length in inches, the rest of their specs (Pitch, Gauge, or Drive Link Count) may differ, making the pair incompatible. Again, the only specifications you really need to ensure compatibility are Pitch, Gauge, and Drive Link Count of both your guide bar and saw chain.
Measuring Your Chainsaw Chain
We'll let you in on a little secret. There are two ways that you can figure out the size of your replacement chain even without access to a product manual:
How to Measure Chainsaw Chain Yourself
To find a chain replacement, you'll need to figure out three numbers:
Measuring Pitch
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/measurepitch_f90216e0-bbfc-4cad-93e9-98cc4634dbf1.png?v=1673900248" />
Chain pitch is the length of the links in the chain. To determine the pitch, you'll need to measure the distance between any three consecutive rivets, then divide the result by 2. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch. Pitch is important because the drive sprocket (and if applicable, the bar nose sprocket) of your guide bar must be the same pitch as the chain.
The most common measurements of pitch you'll see on replacement chain are 3/8" and .325", but may also be .325” Low Profile, .404”, ¼”, ¾”, or ⅜” Low Profile.
Measuring Gauge
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/measuregauge_0483ddc9-e62a-4f66-ba60-2f07f2813d2a.png?v=1673900247" />
Chain gauge, on the other hand, means the thickness of the drive links of the chain. Your saw chain’s gauge can be determined by measuring the portion of the drive link that fits into the groove of the guide bar, usually expressed in thousandths of an inch. For your reference, normal wear can make it difficult to accurately measure chain gauge on a worn chain.
The most common saw chain gauge sizes are .043" (1.1mm), .050" (1.3mm), .058" (1.5mm), and .063" (1.6mm), but may also be .080” or .122”.
Measuring Drive Link Count
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/measuredrivelinkcount_0a578164-88f6-439d-bae4-7c37d4108a1c.png?v=1673900248" />
Count the number of drive links on your old chain loop to get the correct replacement chain. Simply count the drive links around the entire loop of saw chain. The drive link count is the last 3 numbers before the last letter on the Oregon chain part number.
For Example, 72LGX072G = 72 Drive Links; 18HX078E = 78 Drive Links.
Where to LOOK for Measurements on your Saw Chain
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/oregonchainmarking_5c310140-597a-4290-a258-e7fdbacfc773.png?v=1673900250" />

Your old saw chain (that you are replacing) may also contain all the info you need, as the type of saw chain is typically stamped right onto the drive links. The specific saw chain type will provide you with the Pitch and Gauge. For your reference, Stihl uses an extra marking on the tooth link to determine size.Please view the different brands’chain codes, their meanings, and brand-to-brand conversions to Oregon saw chain, below. Once Pitch and Gauge are figured out, all that’s left to do is count and match up the drive links.

Oregon Chain Families: Understanding the Differences
We understand that the needs of woodcutters – professionals and novices – are as diverse as the terrains and environments in which they work.
Oregon has organized their saw chains and guide bars into product families with key characteristics that different users will value. These product families will ensure that you choose the right chain and bar based on your everyday needs. It will make understanding the differences between our products effortless. Feel free to click on the titles below to see our company's saw chain offerings.
Determining Guide Bar & Chainsaw Compatibility
In order to figure out if the Guide Bar and Chainsaw you plan to use together are compatible, you will need to determine (3) key specs for your chainsaw:
(1) “Required Bar Mount,” (2) Pitch, and (3) Gauge
By definition, replacement bars that are interchangeable with the original bar are those that both fit your saw (bar mount and pitch) AND take the same type of chain (pitch and gauge).
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/BarMountCompatible2_0cad2048-2aa8-4c14-9a91-2dacffd727da.png?v=1673900251" />
In practice, there are several different mount, pitch and gauge combinations in use - even in the chainsaws and bars of a single manufacturer - meaning most guide bars are mutually incompatible. Please view the rest of this guide to learn best practices of finding this info yourself.
Measuring Your Guide Bar
Bar Length
Many retailers call out the guide bar's length as a starting point for customers.
While the guide bar length isn’t always necessary to know when trying to determine compatibility, it will help us narrow down what size of bar you’re looking for.
You'll be measuring the usable length of the bar, also called the cutting length, or the called length.
To find the called length of your chainsaw bar, measure it from its front tip all the way back to the cutter closest to the body of the saw.
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/guidebarlength_31882a3b-61e8-4a06-83af-09607ade6d67.jpg?v=1673900247" />
Round this measurement up to the nearest inch. For example, a bar that measures 19 3/4" will actually have a called length of 20".
You then could look for a new bar with a 20" bar length.
Bar Mount
Most chainsaw bars use a superficially similar arrangement of slots and holes for mounting to the chainsaw body. This arrangement is called bar mount (or tail mount). To be compatible, a guide bar and a chainsaw must have a matching bar mount type.
Notice in the photo below the many variations that bar mounts can be oriented. Size and relative location varies between brands and also product lines of a given brand. Sadly, small differences make mounts incompatible: if the holes do not line up, the bar won’t fit or won’t work properly.
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/VaryingBarMounts_e61cf228-75fa-47f6-964c-b3b17228839b.png?v=1673900251" />
To make it easy, we only sell Oregon-brand guide bars. Each chainsaw brand/model will utilize one Oregon bar mount (possibly two, depending if the “old” bar mount has been discontinued/superseded by a newer one).
If you are replacing an old Stihl or Husqvarna guide bar, please take a look at our bar mount conversions below to determine which Oregon bar mount you will need for your chainsaw.
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/Oregonbarmounts_aa5c9c81-7ced-4472-bcc5-2e1172608e78.png?v=1673900249" />
Converting Your Bar Mount to Oregon's Bar Mount
Oregon has dozens of bar mount variations that are used to accommodate an array of different chainsaws and brands. Oregon’s bar mounts are indicated by the last 4 digits of the part number (one letter followed by three numbers). For example, the Oregon 200RNDD025 would utilize bar mount D025.
Depending on the brand and age of guide bar you use, you'll most likely be able to find your guide bar's bar mount by looking at the part number, guide bar etching, or online using your chainsaw's Brand and Model #.
***If you have trouble finding this info for yourself, please reach out to us with your chainsaw's Brand and Model. We understand this can get quite confusing.***
Please view some of the common Stilh/Oregon & Husqvarna/Oregon Bar Mount Conversions, below:
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/stihl_bar_9663d58c-ae69-496b-9813-0aeb8431f2a7.jpg?v=1673973224" />
Stihl bars use three types of bar mounts that can be determined by looking at the first 4 digits of the guide bar part #, usually etched into the guide bar itself:
“3005 - small” (converts to Oregon’s A074);
“3003 - medium” (converts to Oregon’s D025);
“3002 - large” (converts to Oregon’s E031 or E099).
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/H110-0595_3aba30b9-e77c-4142-bffe-26e7f5e8b567.jpg?v=1673973223" />
Husqvarna uses two bar mounts that can be determined by the model number of the chainsaw you're using:
“small” (converts to Oregon’s K095)
“large” (converts to Oregon’s D009).
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/HusqBarMountConversions_cab387b3-bddf-47ab-b84a-aa7835ef3514.png?v=1673900249" />
Where to LOOK for Measurements on your Guide Bar
Your chainsaw’s guide bar may have all the information you are looking for stamped right into it. It can usually be found near the back of the bar, where it mounts to the saw.
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/guidebarspecexample_e1e2c759-efdf-487d-86f9-3d6a6f33eb18.jpg?v=1673900247" />
For instance, in the example above, the chain is 3/8” pitch and .050” gauge with 72 drive links. This, along with the bar mount conversion from above, should be all the information you will need to get the proper replacement guide bar.
Oregon Guide Bar Families: Understanding the Differences
We understand that the needs of woodcutters are as diverse as the terrains and environments in which they work. We’ve organized our guide bars into product families with similar characteristics to help you find the right guide bars for your work.
Chain Maintenance
Sharpening Your Saw Chain
If your saw chain is no longer self-feeding, you have to push on the saw, or the waste material from your saw creates sawdust, it is time to sharpen your chainsaw chain. A good rule of thumb is to sharpen your chain every time you refill gas.
Please view the video below to see how Oregon recommends sharpening saw chain with files:

Determining the Correct File to Use for Your Saw Chain
There are a handful of file sizes that are each meant to sharpen different saw chains, determined by the Pitch of the saw chain. In order to determine the correct file for your needs, you would need to locate the Pitch of your saw chain by using one of the methods mentioned above: finding the code on drive links, etching on bar, or directly measuring the saw chain.
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/ChainPitchtoFileSize_e0c1f021-3288-4be5-bb11-e248f2d61b4a.png?v=1673900250" />
If you have determined the pitch of your saw chain, this table above can be used quite universally with most brands of saw chain.
However, there are some key notes to be careful of when determining the right file:

Saw Chain Lubrication
Fill your oil reservoir each time you fill your chainsaw’s gas tank. Make sure that your saw chain, guide bar, and sprocket are always receiving oil from the saw during operation.
Keep your saw's chain-oiling system filled with clean bar and chain oil. Oregon bar and chain oil is specifically compounded to provide extra high tackiness and prevent "throw off" even under adverse weather conditions.
As a rule of thumb, you should never put used oil or old motor oil in your saw or on your chain. Used motor oil contains metal shavings that reduce the life of your bar and chain. Additionally, lubricating your bar and chain with used motor oil will void your warranty.

CHAINSAW POWER REQUIREMENTS
In general, you will need at least 50cc to run our smallest mill (G777). The more powerful your saw, the easier your milling experience is going to be. Consult the chart to see if your chainsaw has enough power to do the job you want it to do. Under-powered saws will take longer to make a cut and may overheat and possibly fail. You will definitely want to use a ripping chain and take your time. Granberg will not take responsibility for damage caused by using saws that are under-powered. We also recommend against using battery or electric saws.
<img src="https://cdn.shopify.com/s/files/1/0576/5591/8746/files/alaskanmillchartcropped.png?v=1673977182" />
WEDGING TECHNIQUES FOR USE WITH MILLS
It's important to have proper wedges. Depending on the size of the log you are milling, the weight of the slab or beam may be pinching the chain. Using wedges as you move through the cut can help lift the wood out of the way. Wedge early, wedge often. You can buy some on our website here if you don't have any at home.
A good wedge is at least 6″ long, 3″ wide and tapered from 3/4″ to 0″. Best to put at least 5 in your back pocket or tool pouch. After you cut into the log, about 2 feet, put the first wedge into the beginning of your cut. Then put a wedge in every two feet.
Larger, thicker slabs require more support, meaning use more wedges and tapping them in really well.
Lighter, smaller slabs require less support, meaning use less wedges and giving just a quick tap.
CAN I PUT A LARGER MILL ON A SMALLER BAR?
Yes, all of the Alaskan mills we carry can be adapted to fit a smaller bar, because the thickness rails have a channel all the way down that will allow the depth post to be moved. So, if you have a 32” bar, you will want a 36” mill (G778-36). The nose end depth post can be adjusted down to fit the smaller bar.
Likewise, if you have a 36” bar at the moment, but are maybe thinking about investing in a larger bar, you can buy a 48” mill (G778-48) and put it on the smaller bar until you get the upgrade.
One consideration you will have to make is although you can put a larger mill on a smaller bar, the mill size itself will not change, so you will need enough room to operate a 48” mill even if you are only using a 36” bar. This is really only an issue in the thickest of brush. If you’re milling in your driveway or front yard, you shouldn’t have a problem.

VIDEO RECAP
1. THREE important things to consider before milling. One, does your chainsaw have enough power? (see bar/power reference chart). Two, ripping chain is necessary! Three, a first cut system to assist in your first cut. (0:35)
2. Inspect log and debark. Check diameter of log vs the cutting width of mill. Is your mill going to make it through the cut? There may be a section that is too wide. This can be trimmed before milling. (2:00)
3. Mount Alaskan Mill onto bar. Adjust to fit bar. Avoid clamping down on the sprocket nose. Tighten all hardware. The clamping bolts for the bar and end bracket require 10-12 pounds of torque. Tighten evenly. All other carriage bolts use 8-10 pounds of tightening torque. Do not over tighten, this only weakens the bolts. (3:15)
4. Tool kit check. (11:07)
5. Safety Equipment. Chaps, gloves, boots, eye and ear protection are required! (11:51)
6. Make sure your wedges are handy! (12:20)
7. Best way to start your second cut. (13:17)
8. Wedging tips while milling. (14:18)
9. What to look, listen and feel for while milling. (14:54)
10. How to exit the cut. To keep the mill from dipping when exiting cut, put a little back pressure on upright handle and support the powerhead. (17:24)
SELECTING the Rope
Selecting a rope involves evaluating a combination of factors. Some of these factors are straight forward like comparing rope specifications. Others are less quantitative like a preference for a specific color or how a rope feels in your hand.
Fiber and construction being equal, a larger rope will outlast a smaller rope, because of the greater surface wear distribution. By the same token, a stronger rope will outlast a weaker one, because it will be used at a lower percentage of its break strength with less chance of overstressing.
Consider the opinion of professional climbers who may have more experience as to how well a rope performs. Consider also the reputation of the rope manufacturer. Are they involved with and supportive of the arborist industry? Do they stand behind their products with consistent quality and reliable service? Buying unproven ropes because they are a little less expensive is false economy and can lead to disaster
Some things to consider when looking at ropes are:
USING the Rope
Proper use of your ropes, maintaining them, and staying within recommended working loads will allow you to get the most from your rope investment. Working loads are calculated to maximize safety and extend the working life of both climbing and rigging lines. Dirt and grit embedded in the fibers can also significantly shorten rope life. Keep them clean, bagged and properly stored when not in use.
RETIRING the Rope
One of the most frequently asked questions is “When should I retire my rope?” The most obvious answer is before it breaks. But, without a thorough understanding of how to inspect it and without knowing the load history, you are left making an educated guess. Unfortunately, there are no definitive rules nor industry guidelines to establish when a rope should be retired because there are so many variables that affect rope strength. Factors like load history, bending radius, abrasion, chemical exposure or some combination of those factors, make retirement decisions difficult.
Inspecting your rope should be a continuous process of observation before, during and after each use. In synthetic fiber ropes the amount of strength loss due to abrasion and/or flexing is directly related to the amount of broken fiber in the rope’s cross section. After each use, look and feel along every inch of the rope length inspecting for damage as listed below:
There are dozens of pulleys and blocks available for the use of arborists today. However not all are created to the same specifications, and there are many applications which will put high demand on the hardware and for which only certain blocks should be used. While the terms "block" and "pulley" are largely interchangeable, we have divided them into two main groups for clarity:
Other factors to consider when choosing a block or pulley are:
